What Happens To a Football Player's Neurons?

An anonymous reader writes "It seems like every week there's a new story about the consequences of all those concussions experienced by football players and other athletes — just a few days ago, the NY Times reported that some athletes diagnosed with Lou Gehrig's Disease may actually have a neural disease brought on by head trauma. But missing in these stories is an explanation of what head trauma actually does to the brain cells. Now Carl Zimmer has filled in the gap with a column that takes a look at how neurons respond to stress, and explains how stretching a neuron's axon turns its internal structure into 'mush.'"

American Football is not Football

[hernol]

Just to point, we are talking about American Football, not Football. It's not the same.

Take away the football helmets and pads and you might get more contusions and cuts, but less brain damage; it would be more like rugby with the players hitting each other much more softly

College football had become so lethal around 1900 that the game came within an inch of being abandoned.

The 1905 season...brought its rash of casualties. There were twenty-three football deaths. Only a handful took place in intercollegiate play, but one in particular set in motion the movement to reform the game. In a match between Union College and New York University, Harold Moore of Union died after being kicked in the head. Chancellor Henry M. MacCracken of NYU seized the opportunity to summon a reform conference.

In the 1906 season and for two years following, the verdict on the "new football" was generally favorable. In spite of fluctuations in the injury count, the number of deaths dropped to fourteen, fifteen, and ten.

Then, in the fall of 1909, the trend toward a safer game abruptly reversed itself. In a match between Harvard and West Point, the Army captain, Eugene Byrne, exhausted by continual plays to his side of the line, was fatally injured. Earl Wilson of the Naval Academy was paralyzed and later died as a result of a flying tackle. And the University of Virginia's halfback Archer Christian died after a game against Georgetown, probably from a cerebral hemorrhage suffered in a plunge through the line. . "Does the public need any more proof," wrote the Washington Post, "that football is a brutal, savage, murderous sport? Is it necessary to kill many more promising young men before the game is revised or stopped altogether?" President David Starr Jordan of Stanford referred to football as "Rugby's American pervert..."

Early headgear, seldom worn consistently, shielded the ears and surface of the head but gave inadequate protection to the skull and brain. After World War I a sponge-rubber lining was added to the crown of the helmet, and by the late 1930s a sturdy leather helmet with an inner felt lining was being used. But it was not until 1943 that all players were required to wear headgear. The plastic helmet, which distributes shock more evenly, was introduced in the 1940s amid objections reminiscent of those that accompanied the original solely leather helmets. Some critics argued--and still do--that the hard plastic helmet, used as an offensive weapon, has as much potential for causing as for preventing serious injuries. Inventing Modern Football
